Common Grackle Close Up

The close up picture of this Common Grackle was taken at the New York Botanical Gardens. The picture of this Common Grackle was taken with the CANON EOS 7D and the CANON 100-400 lens.

The blues, greens and other iridescent variations in birds arise from the physical presence of minute structures on the surface of the feathers which reflect only one wavelength of light.
